we have a station with two redundant cpu 414-4H he first cpu is on stop and signal an external default, an automation think there is a problem in the cpu even if it does not display an internal error !!! !
me I want to know if this can happen and really there's a chance that the cpu is defaulting and ( he does not arrive to display the internal default ? )
the second question is if it is replaced by another of the same cpu reference of course , there's a chance that he can go to run , so that START confirmed what this person said on the first cpu ?
The error in the CPU 0 :
